This book was released on 2017-12-20 with total page 494 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from A Memoir on the Palaeozoic Reticulate Sponges Constituting the Family Dictyospongidae So rapid has been the growth of these collections and so generous the disposition of all collectors and students toward the perfecting of this monograph, that to-day we present descriptions of about thrice the number of specific forms recognized as such, seven years ago. This wonderful increase is not especially a matter for congratulation, save that it serves to show the amazing diversity of these siliceous sponges in late Devonian and early Carboniferous faunas. The species and genera are established in accordance with the best standards attainable for these variable organisms. Future collections and observations may show that these divisions are not in all cases sharply defined they will undoubtedly Show that the present account of this organic element in these ancient rocks is far from being complete. In 1892, Mr. Clarke undertook a revision of all previous work upon these fossils and this, with the elaboration of new material, he has carried forward to its present state.

Available in PDF, EPUB and Kindle. Book excerpt: Fossil and Recent Sponges contains articles on taxonomic, phylogenetic and ecological aspects of sponges of both biological and paleontological interest. They focus on three main topics: phylogeny and systematics, biology, and paleoecology of sponges. The reader is offered an overview over the most important aspects of current sponge research: - establishment of a new taxonomy based on mono phyletic groups (phylogenetic systematics) including recent and fossil taxa - new concepts of the biomineralisation of sponge skeletons - palaeoenvironmental analysis of fossil sponge buildups.

Download or read book A New Silurian (Llandovery, Telychian) Sponge Assemblage from Gotland, Sweden written by Freek Rhebergen and published by John Wiley & Sons. This book was released on 2014-02-27 with total page 161 pages. Available in PDF, EPUB and Kindle. Book excerpt: A newly discovered, diverse sponge fauna of early Silurian age, is described from Gotland, Sweden. This is the first Silurian sponge assemblage known from Baltica, and the only diverse Llandoverian assemblage known worldwide. The fauna includes 20 genera and 29 species, of which three genera and six species are new. Eighteen species are new to Baltica. The fauna shows strong similarities to later Silurian assemblages in Arctic Canada, but one endemic species comprises ca. 50% of the fauna. The fauna shows that lithistid sponges recovered well from the late Ordovician extinction in some areas, and became widely spread in the early Silurian. In contrast, non-lithistid sponges like, such as hexactinellids, appear to have evolved rapidly during the Late Ordovician – early Silurian interval, and some modern groups probably originated in inshore habitats.

Available in PDF, EPUB and Kindle. Book excerpt: Receptaculitids are extinct high-level fossils that provide a window into the history of life. After the discovery and analysis of a deposit of phosphatized receptaculitids on the Baltic Sea island of Öland, the authors conclude that receptaculitids possess an attribute not found in any other group of organisms, living or fossil.

Download or read book Systema Porifera written by John N.A. Hooper and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 1779 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research whilst compiling this book has uncovered a fauna about twice the size as that previously published in the literature and consequently Systema Porifera revises and stabilizes the systematics of the phylum to accommodate this new knowledge in a contemporary framework. Practical tools (key illustrations, descriptions of character) are provided to facilitate the assignment of approximately 680 extant and 100 fossil genera. Systema Porifera is unique making sponge taxonomy widely available at the practical level of classification (genera, families, order). It is a taxonomic revision of sponges and spongiomorphis (such as sphinctozoans and archaeocyathans) based on re-evaluation of type materials and evidence. It is also a practical guide to sponge identification providing descriptions and illustrations of characters and interpretation of their importance to systematics. Systema Porifera addresses many long standing nomenclatural problems and provides a sound baseline for future debate on sponges and their place in time and space. Systema Porifera describes 3 classes, 7 subclasses, 24 orders, 127 families and 682 valid genera of extant sponges (with over 1600 nominal generic names and an additional 500 invalid names treated). Treatment of the fossil fauna is less comprehensive or critical, although 6 classes, 30 orders, 245 families and 998 fossil genera are mentioned. Keys to all recent and many fossil taxa are provided.
